Skunk2 Racing Ultra Street Intake Manifold for Honda K-Series K20A K20A2 K20Z1 K24A1

VEHICLE TYPE:  2002 - 2005 Honda Civic (2.0L Si) 2002 - 2006 Acura RSX (2.0L Base/Type S) MFG#: 307-05-0600 Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 71mm throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to 6.85” long intake runners with smooth transitions allowing the Ultra Street Intake Manifold to really move some air!
